Trichuris
''Trichuris'', often referred to as whipworms (which typically refers to ''T. trichiura'' only in medicine, and to any other species in veterinary medicine), is a genus of parasitic worms from the roundworm family Trichuridae, which are helminths. The name whipworm refers to the shape of the worm; they look like whips with wider "handles" at the posterior end. The name ''Trichocephalus'' is sometimes used for this genus. Species The genus ''Trichuris'' includes over 20 species, which infect the large intestine of their host, including: * '' Trichuris trichiura'' (sometimes ''Trichocephalus trichiurus'') – causes trichuriasis in humans * '' Trichuris campanula'' (cat whipworm) * ''Trichuris serrata'' (cat whipworm) * '' Trichuris suis'' (pig whipworm) * '' Trichuris muris'' (mouse whipworm) * '' Trichuris vulpis'' (dog whipworm) A new species – as yet unnamed – has been identified in François’ leaf monkey (''Trachypithecus francoisi''). Other species in this genus i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whipworm
''Trichuris trichiura, Trichocephalus trichiuris'' or whipworm, is a parasitic roundworm (a type of helminth) that causes trichuriasis (a type of helminthiasis which is one of the neglected tropical diseases) when it infects a human large intestine. It is commonly known as the ''whipworm'' which refers to the shape of the worm; it looks like a whip with wider "handles" at the posterior end. Life cycle The female ''T. trichiura'' produces 2,000–10,000 single-celled eggs per day. Eggs are deposited from human feces to soil where, after two to three weeks, they become embryonated and enter the "infective" stage. These embryonated infective eggs are ingested by hand-mouth or through formites and hatch in the human small intestine, exploiting the intestinal microflora as a stimulus to hatching. This is the location of growth and molting. The infective larvae penetrate the villi and continue to develop in the small intestine. The young worms move to the caecum and penetrate th ...

Trichuriasis
Trichuriasis, also known as whipworm infection, is an infection by the parasitic worm ''Trichuris trichiura'' (whipworm). If infection is only with a few worms, there are often no symptoms. In those who are infected with many worms, there may be abdominal pain, fatigue and diarrhea. The diarrhea sometimes contains blood. Infections in children may cause poor intellectual and physical development. Low red blood cell levels may occur due to loss of blood. The disease is usually spread when people eat food or drink water that contains the eggs of these worms. This may occur when contaminated vegetables are not fully cleaned or cooked. Often these eggs are in the soil in areas where people defecate outside and where untreated human feces is used as fertilizer. These eggs originate from the feces of infected people. Young children playing in such soil and putting their hands in their mouths also become infected easily. The worms live in the large bowel and are about four centimet ...

Trichuris Discolor
''Trichuris discolor'', commonly known as a whipworm, is a nematode belonging to the genus ''Trichuris''. The species was discovered by Otto Friedrich Bernhard von Linstow in 1906 and primarily infects cows. However, they can also infect sheep and goats. Like ''Trichuris ovis'', ''T. discolor'' is known to be located in any region that their hosts are located. There have been specific reports of this species being found in Japan, Indo-Pakistan, and North America. Information regarding the species' general life cycle and egg development can be seen in the ''Trichuris'' page. Morphology and differentiation from ''T. ovis'' Despite inhabiting the same hosts, ''T. discolor'' and ''T. ovis'' are distinct species. The size of male and female ''T. discolor'' whipworms are 33.9-50.68mm and 36.0—59.0mm respectively. The spicule of ''T. discolor'' is 0.94-1.30mm long and has a rounded tip, whereas the spicule of ''T. ovis'' is 4.18-5.62mm long and has a pointed tip. In addition to the ...

Trichuris Vulpis
''Trichuris vulpis'' is a whipworm that lives in the large intestine of canines in its adult stages. Out of different types of worms, ''Trichuris vulpis'' is one of the smaller worms with a size ranging from 30–50 mm in length. As the name suggests, the worm has a whip-like shape with distinct features including a small, narrow anterior head, which is the digestive part of the worm, and a larger posterior tail, which is the reproductive part of the worm. Eggs from ''T. vulpis'' are oval shaped with bipolar plugs and contain a thick outer shell. Their sizes range from 72–90 μm in length and 32–40 μm in width. Because of their thick outer shell, ''T. vulpis'' eggs are very resistant to environmental extremes such as freezing or hot temperatures, thus allowing for their long viability in the outside world. Life cycle The life cycle of ''Trichuris vulpis'' begins with the adult whipworms living in the large intestines of dogs. ''T. vulpis'' lay many eggs in t ...
